One of the latest posts is something that you can share with the children, and they just might get it. "Charlotte Changes" shows a spider who shed her skin, and then built herself a new web, too.
The whole web site is at Wormspit.com. I recommend it. He has a great perspective on life, and excellent photos to go along with it. From bees to baby squash to chickens (FREEBIRD!), it's a fun look at urban farming.
